Well I did edit the ifcfg-* files, and networkmananger didn't agree and destroyed /etc/resolv.conf. Now I could say that networkmanager should be able to detect when someone edits the relevant files and act accordingly. A simple flag-entry like "nm-touch: [yes | no]" in resolv.conf might help a lot already; it could even be in form of a comment which only networkmanager understands so it doesn't interfere with anything else that uses the file. It would still be a very ugly solution ... It would be better if the installer gave you a choice whether to use networkmanager or not. I guess they need to fix the dependencies of it first ... What is the procedure to make suggestions like that?

The most famous traditional capital-lettered files are (IMHO): /usr/bin/Xorg /etc/X11/ /var/log/Xorg.0.log Next on the list are /etc/ImageMagick/, /etc/NetworkManager/, /etc/PackageKit/, and so on... By the way, I find it very braindead to search for documentation or configuration on NetworkManager, and not ever try the obvious "man networkmanager". And the man is even case-insensitive, for your convenience. In addition, in the SEE ALSO section it points you to read the "man networkmanager.conf", which in turn tells you the exact path to the configuration files at the very top of the document.

Why do you consider such a scenario to be strange? The dhcp was invented for precisely this purpose. It is widely used on laptops and other mobile devices, in home&office environments for desktops, etc. Typically only servers need to have a static IP. And even that can be remote-configured by the dhcp server. In fact, the dhcp server itself is the only one requiring a static manually-configured IP. Everything else can be configured by a remote dhcp server. > Anyway, I still want to know, even with networkmanager disabled.

The dhcp server requires a NIC with a static IP (it cannot serve itself). If NetworkManager is configured so that it assigns a static IP to that particular interface, dhcp will be happy, and everything will work well. It can even serve the IPs for other NICs on the same machine (if any are present), and NetworkManager will pick those up and configure them, if they are set up to use dhcp... ;-) > > Regarding trying to find its configuration files, I would have tried > > something like: locate -i networkmanager |grep etc I doubt that in normal circumstances one would ever need to manually edit files in /etc/NetworkManager/. All configuration files that are related to the actual network interfaces (used by NM) are in /etc/sysconfig/network-scripts/, among which the most interesting are the ifcfg-* files. Those are probably the only files that one could be motivated to hand-edit. At least in normal circumstances, and in the absence of a GUI utility.

Letting us know will help you get better replies. There does appear to be some NetworkManager interface through the command line. Dunno whether it's going to be of any use to you, though. As may have been pointed out in this thread, but definitely in the past, NetworkManager is probably not be suitable for servers. It is geared towards having something else configure your network, usually a server is self-configured, or at least the central server is (the one everything else relies on).

I don't think I have. It's more Fedora being silly having two different and conflicting things installed by default at the same time without giving users a choice which one to use, without sufficient documentation about any of them and with dependencies on networkmanager that need to be fixed. -- Fedora 17 -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

I do not know > if this situation has changed. I have had the same impression. It might be nice to have on a mobile computer with arbitrary internet connections *if* it works. Unfortunately, the installer doesn't leave you a choice. Obviously, networkmanager is unable to handle a change in the configuration, so the only situation in which it /might/ work is when you don't touch it and use DHCP. Of course, if I was using DHCP, the DHCP server would run on the same computer as networkmanager, and that probably won't work, either --- especially not during the installation.

The installer forced me to use it, and networkmanager seems to be still trying to enforce an outdated configuration when it is enabled. That's why I keep asking how to change it and where it stores its configuration. -- Fedora 17 -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

I believe that NM over-writes /etc/resolv.conf if it cannot establish the specified connection. In my opinion this is silly; but that is what NM does. If you don't want NM to manage your connection you should say so in the above ifcfg file.

Tim: > > _EXACTLY_ how are you giving it the data? Lee: > I was using system-config-network and editing some files when it didn't > work. Well, unless things have changed, then you're fighting two things against each other. System-config-network directly controls the network settings. NetworkManager does whatever it does, dynamically. NetworkManager will clobber settings set elsewhere, unless you specifically configure NetworkManager to leave them alone. You'd need to that through NetworkManager's own interface, or through the configuration files that it pays attention to. > > * Are you configuring network manager, through its own interface? > I thought system-config-network is the interface for it.

And the lack of useful documentation doesn't help. > How do you configure it? If using Gnome, there's a desktop taskbar icon for NetworkManager, it lets you pick a network out of a list of available networks (if there are several to choose from), and there's an edit connections menu item to customise particular choices. They could be fully automatic (the client is remotely set by a DHCP server), or you can choose to allow some things to be set by a DHCP server, other things to be manually set, or everything manually set. That said, prior experience has shown that NetworkManager is geared towards automatically configuring DHCP clients by the DHCP server. If you don't have a DHCP server, it can be easier to disable NetworkManager, and use the old system-config-network, rather than try to set up manual configurations through NetworkManager. I do not know if this situation has changed. If you do not use DHCP, then I'm not sure how, nor why, NetworkManager would be fiddling with things. Other than, perhaps, automatically assigning a random link-local address to the ethernet interface, because no DHCP server assigned one. -- [tim@localhost ~]$ uname -rsvp Linux 3.6.6-1.fc17.x86_64 #1 SMP Mon Nov 5 21:59:35 UTC 2012 x86_64 All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I will only read messages posted to the public lists. -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

I disabled networkmanager and so far, it seems to work (haven't rebooted yet, though). If my theory about what happened is correct, that would mean that networkmanager actually did kinda work fine and was only doing what it was supposed to.
